  Hereinafter, the mobile device 10 according to an embodiment will be described in detail with reference to FIGS. FIG. 1 is a block diagram showing the configuration of the mobile device 10.

  The mobile device 10 is an information device that is used while being carried by a user. As the mobile device 10, a mobile phone, a smart phone, a PHS (Personal Handy-phone System), a PDA (Personal Digital Assistant), or the like can be adopted. In this embodiment, the mobile device 10 is a smart phone. To do. The mobile device 10 has a telephone function, a communication function for connecting to the Internet, etc., a data processing function for executing a program, and the like.

  As shown in FIG. 1, the mobile device 10 includes a display 12, a touch panel 14, a speaker 15, a calendar unit 16, a sensor unit 20, an imaging unit 30, a clothing detection unit 41, a flash memory 50, And a control unit 60. In addition, each said part shall be provided in the main-body part (housing | casing) 11 shown in FIG.

  The display 12 displays images, various information, and operation input images such as buttons. As an example, the display 12 is a device using a liquid crystal display element.

  The touch panel 14 is an interface through which information corresponding to the touch by the user can be input to the control unit 60. Since the touch panel 14 is incorporated in the surface of the display 12 or the display 12, the user can intuitively input various information by touching the surface of the display 12.

  The calendar unit 16 acquires time information such as year, month, date, and time and outputs the time information to the control unit 60. Note that the calendar unit 16 further has a timekeeping function.

  The sensor unit 20 has various sensors. In the present embodiment, the sensor unit 20 includes a position sensor 21, a biosensor 22, a posture sensor 23, a thermohygrometer 24, an electric field sensor 25, an odor sensor 26, an acceleration sensor 27, an angular velocity sensor 28, and a brightness sensor 29. Suppose you are.

  The position sensor 21 includes a GPS (Global Positioning System) module. The GPS module is a sensor that detects the position (for example, latitude or longitude) of the mobile device 10. Further, the position sensor 21 may include a sensor that detects the position of the mobile device 10 based on the result of communication with the wireless LAN base station.

  The biological sensor 22 is a sensor that is provided in a part of the main body 11 of the mobile device 10 (a portion that is easily touched by the user's hand) and acquires the state of the user holding the mobile device 10. As an example, the biosensor 22 acquires a user's body temperature, blood pressure, pulse, sweat rate, and the like. As an example of such a biosensor 22, light is emitted from a light emitting diode toward a user as disclosed in Japanese Patent Laid-Open No. 2001-276012 (US Pat. No. 6,526,315). A sensor that detects a pulse by receiving light reflected from a user according to light, or a wristwatch-type biosensor disclosed in Japanese Patent Application Laid-Open No. 2007-215749 (US Publication No. 2007-191718). Can be adopted.

  The biosensor 22 includes a sensor (pressure sensor) that acquires information (for example, gripping force) related to the force with which the user holds the mobile device 10. Such a pressure sensor can detect that the user holds the portable device 10 and the magnitude of the force that holds the portable device 10. In addition, the control part 60 mentioned later may start acquisition of the information by another biological sensor in the stage which detected that the user hold | maintained the portable apparatus 10 with the pressure sensor. In addition, the control unit 60 turns on other functions (or returns from the sleep state) when the pressure sensor detects that the user holds the portable device 10 while the power is on. Such control may be performed. Further, a sweat sensor or a heart rate sensor that detects a heart rate may be provided as the biosensor 22.

  The posture sensor 23 is provided inside the portable device 10 and detects the posture of the imaging unit 30 described later by detecting the posture of the portable device 10. As the attitude sensor 23, a configuration in which a plurality of sensors that detect the attitude in the uniaxial direction depending on whether or not the small sphere moving by gravity blocks the infrared light of the photo interrupter can be adopted. However, the present invention is not limited to this, and the orientation sensor 23 may be a triaxial acceleration sensor, a gyro sensor, or the like.

  The thermohygrometer 24 is an environmental sensor that detects the ambient temperature and humidity of the portable device 10. Note that a thermometer and a hygrometer may be separately provided in the portable device 10 instead of the thermohygrometer 24. Note that the thermohygrometer 24 may be configured to also serve as a function of detecting the body temperature of the user by the biosensor 22.

  The electric field sensor 25 is a sensor that detects an electric field existing around the human body. Since the electric field around the human body changes due to muscle expansion and contraction or the like, when the electric field detected by the electric field sensor 25 shows a predetermined fluctuation, the portable device 10 exists near the human body (for example, an outerwear) Is held in the chest pocket and pants pocket). When the electric field detected by the electric field sensor 25 does not change, it can be seen that the portable device 10 is not near the human body (for example, stored in a bag or placed on a desk). The electric field sensor 25 may be an optical electric field sensor that detects an electric signal by replacing a voltage change with the intensity of light, or a trident electric field that detects an electric signal by replacing a voltage change with the intensity of magnetism. A sensor may be used.

  The odor sensor 26 is a sensor that includes a metal oxide semiconductor and can detect a specific odor component. In this embodiment, for example, the odor sensor 26 is a sensor that can detect the smell of sweat (ammonia component). It shall be. The detection result by the odor sensor 26 is used to determine the clothes cleaning time.

  As the acceleration sensor 27, a piezoelectric element or a strain gauge can be used. The detection axis of the acceleration sensor 27 can be in three axis directions. The angular velocity sensor 28 includes a gyro sensor and detects the angular velocity of the mobile device 10. Here, in this embodiment, using the detection results of the acceleration sensor 27 and the angular velocity sensor 28, is the user walking with the portable device 10 in the outer chest pocket (point A in FIG. 2A)? It is determined whether the user is walking in a pants pocket (point B in FIG. 2A). Specifically, when the user is walking, the angular velocity around the axis perpendicular to the plane including the traveling direction and the vertical direction (see FIG. 2B) is determined when the portable device 10 is held in the breast pocket. Is substantially 0 (FIG. 2 (c)), but the angular velocity vibrates with a positive or negative value when held in the pocket of the pants. Thus, the holding position of the portable device 10 can be determined by monitoring the change in the angular velocity. In addition, what is necessary is just to make it the control part 60 determine about a user's advancing direction based on the change of the acceleration at the time of a user's walk.

  Even if only the acceleration sensor 27 is used, it is possible to determine whether the user is walking with the portable device 10 in the pocket of the jacket or walking in the pocket of the pants. Specifically, as shown in FIG. 3 (a), the acceleration of the chest pocket portion of the user becomes almost zero after a predetermined time has elapsed since the start of walking, but the acceleration of the pocket portion of the pants is shown in FIG. 3 (b). ) As shown. Thus, the holding position of the mobile device 10 can be determined by monitoring the change in acceleration.

  Returning to FIG. 1, the brightness sensor 29 includes an illuminance meter and the like, and is used to determine whether the portable device 10 is in a pocket or is held by a hand.

  The imaging unit 30 includes a camera, and performs imaging in accordance with an imaging instruction from the user via a touch panel and an imaging instruction from the control unit 60. As illustrated in FIG. 4, the imaging unit 30 can capture a range up to the face and the chest (for example, a 500 mm square range illustrated in FIG. 4) while the user is operating the mobile device 10. It is provided on the same surface as the display 12 and the touch panel 14, and the imaging direction and the angle of view are adjusted and set. Note that the imaging unit 30 may be provided on a surface (for example, the back surface) different from the display 12 or the touch panel 14 so that the user's pants are captured when the user is in the state illustrated in FIG.

  The clothing detection unit 41 detects a user's clothing imaged by the imaging unit 30 and is compared with clothing data stored in a flash memory 50 described later, and is not stored in the clothing data in the flash memory 50. In this case, it is stored in the flash memory 50 as clothes newly purchased by the user.

  The flash memory 50 is a nonvolatile semiconductor memory. The flash memory 50 stores a program for controlling the mobile device 10 executed by the control unit 60, various parameters for controlling the mobile device 10, a database to be described later (see FIGS. 6 and 9), and the like. .

  The control unit 60 has a CPU and controls the entire mobile device 10 in an integrated manner. In the present embodiment, the control unit 60 images the user's clothes at an appropriate timing, determines the smell of the user's clothes, and predicts the cleaning time of the user's clothes.

  Next, processing ((1) imaging processing, (2) odor determination processing, (3) cleaning time prediction processing) by the control unit 60 of the present embodiment will be described in detail. Each process is executed in parallel.

(1) Imaging Process First, the imaging process by the control unit 60 will be described in detail along the flowchart of FIG. Note that the processing in FIG. 5 is processing in which imaging by the imaging unit 30 is performed at a timing at which the user's clothes can be imaged, and information based on the imaging result is recorded in the clothes DB (FIG. 6).

  In the process of FIG. 5, in step S <b> 10, the control unit 60 stands by until a predetermined time elapses from the previous imaging. Here, it is assumed that, for example, 30 minutes is set as the predetermined time. If the determination in step S10 is affirmative, the process proceeds to step S12.

  If transfering it to step S12, the control part 60 will judge whether a user's clothes can be imaged based on the detection result of the biosensor 22 and the attitude | position sensor 23. FIG. More specifically, the control unit 60 can capture an image of the user based on whether or not the user is holding the mobile device 10 based on the detection result of the biological sensor 22 and based on the detection result of the posture sensor 23. It is determined whether or not it is facing the direction. If the determination in step S12 is affirmed, the process proceeds to step S14. If the determination is negative, the determination in step S12 is repeated.

  If transfering it to step S14, the control part 60 will instruct | indicate the imaging part 30, and will acquire date information from the calendar part 16 while imaging a user's clothing.

  Next, in step S <b> 16, the control unit 60 instructs the clothing detection unit 41 to specify the clothing ID. The clothing detection unit 41 identifies the clothing ID by pattern matching between the clothing image captured by the imaging unit 30 and the clothing image that has been captured in the past and the clothing ID has already been assigned. In addition, when it does not correspond with the clothes already imaged in the past (it is new clothes), the clothes detection part 41 shall allocate new clothes ID.

  Next, in step S18, the control unit 60 refers to the clothes DB (see FIG. 6A), and determines whether or not the specified clothes ID is the same clothes ID as that at the previous imaging. Note that the clothing DB includes fields for date and time, clothing ID, elapsed time, and corrected elapsed time, as shown in FIG. In the date / time field, the date / time of image capturing is input. In the clothes ID field, the clothes ID specified in step S16 is input. In the elapsed time field, the time of wearing the same clothes is entered. In the correction elapsed time field, a value obtained by correcting the time when the same clothes are worn on the basis of the next imaged image is input.

  When the determination in step S18 is affirmed, the process proceeds to step S20, and the control unit 60 adds and stores the elapsed time of the clothes DB. More specifically, for example, in FIG. 6A, in the state where data up to “2012/07/01 11:00:00” is stored in the clothes DB, “2012/07/01 14 : 30: 00 "is captured. In this case, the control unit 60 stores 4.5h obtained by adding the elapsed time 3.5h to the past elapsed time 1.0h in the clothing DB. In addition, after the process of step S20 is performed, it returns to step S10.

  On the other hand, if the determination in step S18 is negative, that is, if the clothes are different from those at the previous imaging, the process proceeds to step S22, and the control unit 60 reads the past elapsed time of the same clothes ID. As shown in FIG. 6B, if there is no information about the same clothes (clothes ID = B) in the past, 0.0h is read as the elapsed time.

  Next, in step S24, the control unit 60 corrects the elapsed time of the previous clothing. In this case, the control unit 60, for example, the date and time “2012/07/01 14:30:00” at which the clothing ID = A was last imaged and the clothing ID = B clothing shown in FIG. The time (3.5h) between the date and time when the image was first imaged “2012/07/01 18:00:00” is considered to be wearing the clothes with the clothes ID = A, and the elapsed time is corrected. Set 8.0h by adding 3.5h to time 4.5h. However, the present invention is not limited to this, and it may be estimated that the clothes having the clothes ID = A are worn in the half of the time 3.5h described above and the clothes having the clothes ID = B are worn in the other half. Good. In addition, after the process of step S24 is performed, it returns to step S10.

  After returning to step S10, the processes and determinations of steps S10 to S24 are repeated, and clothes information is added to the clothes DB as needed.

  FIG. 7A shows the case where the clothes with clothes ID = A are captured at the date “2012/07/02 08:00:00” (after steps S22 and S24). (B) shows a case where the clothes of clothes ID = A are imaged at the date “2012/07/02 10:00:00” (when step S20 is performed).

(2) Odor Determination Processing Next, the odor determination processing by the control unit 60 will be described in detail along the flowchart of FIG.

  In the process of FIG. 8, in step S30, the control unit 60 determines whether or not there is a predetermined change in the detection value of the electric field sensor 25 and the brightness is equal to or less than the predetermined value. If the determination here is affirmative, that is, if it can be determined that the mobile device 10 is held near the human body and is in the pocket, the process proceeds to step S34, and the control unit 60 It is determined that there is a mobile device in the vicinity, and the process proceeds to step S36. If the determination in step S30 is negative, the process proceeds to step S32, and the control unit 60 determines that there is no portable device near the clothes, and returns to step S30.

  After proceeding to step S36 via step S34, the control unit 60 detects an odor (such as the smell of sweat) using the odor sensor 26. Next, in step S38, the control unit 60 determines whether or not to smell, that is, whether or not the smell exceeds a predetermined allowable range. If the determination is negative, the process returns to step S30. If the determination is positive, the process proceeds to step S40.

  When the process proceeds to step S40, the control unit 60 uses the angular velocity sensor 28 and the acceleration sensor 27 to detect the holding position of the portable device 10 (whether it is a chest pocket of an outer jacket or a pants pocket) (see FIG. 2). . In step S40, the control unit 60 may detect the holding position of the mobile device 10 using the acceleration sensor 27 (see FIG. 3).

  Next, in step S42, the control unit 60 determines whether or not the portable device 10 is held in the chest pocket of the jacket. When determination here is affirmed, it transfers to step S44 and the control part 60 determines with "a jacket is smelling". On the other hand, if the determination in step S42 is negative, the process proceeds to step S46, and the control unit 60 determines that “trousers smell”. After steps S44 and S46, the process proceeds to step S48.

  In step S48, the control unit 60 refers to the clothing DB, and records the determination result of step S44 or S46 in the odor DB (FIG. 9A) in association with the clothing ID and the elapsed time. Here, as shown in FIG. 9A, the odor DB has fields of odor detection date / time, clothing ID, up / down determination, and wearing time. In the odor detection date / time field, the date / time when step S38 was affirmed is input, and in the clothing ID field, the clothing ID corresponding to the odor detection date / time (the latest clothing ID recorded in the clothing DB) is input. The In addition, a jacket or trousers (determination result in steps S44 and S46) is input in the up / down determination field, and the latest elapsed time recorded in the clothes DB is input in the wearing time field.

  Next, when the process proceeds to step S50, the control unit 60 notifies the cleaning time and the deodorization treatment time via the display 12 and the speaker 15. In this case, the control unit 60 may display a message such as “the cleaning time for the currently worn outerwear has arrived” on the display 12. The control unit 60 may output a warning sound from the speaker 15. Moreover, you may make it the control part 60 alert | report a deodorizing treatment (skin care, bathing, shower) with respect to a user.

  Next, in step S52, the control unit 60 updates the predicted odor occurrence time DB (see FIG. 9B). Here, as shown in FIG. 9B, the odor occurrence prediction time DB includes fields of clothes ID, up / down determination, and prediction time. The predicted time is an average of the actual time until an odor occurs in each dress. Therefore, in step S52, the control unit 60 recalculates the predicted time using the latest wearing time of the odor DB, and updates the odor occurrence predicted time DB. The predicted odor generation time DB (see FIG. 9B) is based on the seasonal information by the calendar unit 16 and the temperature / humidity measured by the thermohygrometer 24. A correction value (or correction coefficient) for shortening may be prepared, and a correction value (or correction coefficient) for increasing the prediction time may be prepared in an environment where sweating is difficult. Instead of this, or in addition to this, a correction value (or correction coefficient) that shortens the prediction time as the value of the sweat sensor of the biological sensor 22 or the heart rate sensor increases may be prepared. .

  Thereafter, the process returns to step S30, and thereafter, the processes and determinations of steps S30 to S50 are repeated.

  It should be noted that if the odor is no longer detected in the clothes once the odor has been detected, it is considered that cleaning or deodorizing treatment has been performed. In such a case, the control unit 60 may delete the clothing data from the clothing DB (reset the elapsed time). Further, there are cases where the smell is not detected and the elapsed time of the clothes DB becomes long. In such a case, the clothing data may be deleted from the clothing DB (elapsed time is reset) when the elapsed time exceeds a predetermined threshold.

(3) Cleaning Time Prediction Processing Next, cleaning time prediction processing by the control unit 60 will be described with reference to FIG. The process in FIG. 10 is a process for predicting the time when the odor occurs in the clothes before the odor is generated in the clothes and informing the user.

  In the process of FIG. 10, in step S <b> 60, the control unit 60 waits until clothing is imaged. In this case, the control unit 60 proceeds to step S62 when the process of step S14 of FIG. 5 is performed.

  If transfering it to step S62, the control part 60 will refer to clothing DB (FIG.7 (b) etc.). Next, in step S64, the control unit 60 refers to the predicted odor occurrence time DB and determines whether or not the current wearing time of the clothes has exceeded the expected time. If the determination here is affirmative, it can be determined that there is a high possibility that an odor will occur in the near future. Therefore, in step S66, the control unit 60 notifies the arrival of the cleaning time. Thereafter, the process returns to step S60.

  On the other hand, if the determination in step S64 is negative, the control unit 60 proceeds to step S68 and performs position acquisition using the position sensor 21 (for example, a GPS module). In addition, when acquiring a detailed position (for example, a position in a building), the position is acquired using a sensor that detects a position using a communication result with the wireless LAN base station together with the GPS module. It is good.

  Next, in step S70, the control unit 60 refers to the map DB stored in the flash memory 50 (latitude and longitude information is associated with information such as a building) and identifies the user's whereabouts. To do. In addition, when position acquisition using a position sensor cannot be performed in a building, the position information obtained immediately before entering the building may be used.

  Next, in step S72, the control unit 60 determines whether or not the user exists in a place where the user can easily smell (for example, a pub, a pachinko shop, a station smoking area, or the like). If the determination is negative, the process returns to step S60. If the determination is positive, the process proceeds to step S74.

  When the process proceeds to step S74, the control unit 60 corrects the wearing time of the clothes in consideration of the place. For example, the control unit 60 may correct the wearing time by multiplying the time at which the user was easily smelled by a predetermined number of times. It is also possible to perform correction by adding a predetermined number to.

  Next, when the process proceeds to step S76, the control unit 60 determines whether or not the corrected wearing time exceeds the expected odor occurrence time. If the determination is negative, the control unit 60 returns to step S60. If the determination is positive, the control unit 60 notifies the user of the arrival of the cleaning time in step S66, and then returns to step S60. Note that the arrival of the deodorizing treatment time of the clothes may be notified instead of the arrival of the cleaning time.

  In addition, after returning to step S60, the processes and determinations of steps S60 to S76 are repeated. And whenever a cleaning time comes, the alert | report to a user is performed.

  As described above in detail, according to the present embodiment, the control unit 60 can be carried at any position of the user's body according to the detection results of the acceleration sensor 27 and the angular velocity sensor 28 that detect the movement of the user's body. Since it is determined whether the device 10 is held, it is possible to determine the holding position of the portable device 10 (for example, a chest pocket of an outer jacket or a pants pocket) with high accuracy based on the movement of the user. The holding position of the mobile device 10 determined as described above can be used when realizing various functions of the mobile device 10.

  In the present embodiment, the control unit 60 detects that the user is in contact with or close to the user's body based on the detection result of the electric field by the electric field sensor 25, so that the user is in the vicinity of the body (such as a pocket of clothes). Thus, it can be determined with high accuracy whether the portable device 10 is held or whether the portable device 10 is held in a bag.

  In this embodiment, since the control unit 60 acquires the detection result of the odor sensor 26, the position where the portable device 10 is held and the detection result of the odor sensor 26 are used to determine the position where the odor is generated. It can be determined with high accuracy. In this case, it is not necessary for the user to voluntarily bring the mobile device 10 close to clothes, so that it is convenient for the user. Moreover, since the control part 60 alert | reports the cleaning time arrival (information regarding deodorization) via the display 12 or the speaker 15, the user can clean clothes at an appropriate timing. In the present embodiment, since the imaging unit 30 captures the clothes worn by the user at the timing when the user uses the mobile device 10, the control unit 60 determines from which clothes the odor is generated. Can be specified.

  In the present embodiment, the mobile device 10 includes the position sensor 21, and the control unit 60 identifies the user's whereabouts based on the detection result of the position sensor 21, and considers the whereabouts to clean clothes. Therefore, it is possible to perform notification based on the prediction of the appropriate cleaning time and the prediction result in consideration of the case where the user is in a place where it is easy to smell.
